Jay's E-portfolio - science fair

Thinking
Learning Intention : Apply brainstorming skills
A. My investigation is about
To check if there is any acid in the rain in Howick.
B. Feedback/feed forward
Mr Read: This is a good topic to test and and try to see if you can collect some rainwater at school.
Planning
Learning Intentions : ~ Develop science fair vocabulary and comprehension of terms ~ Plan a fair test.
A. My investigative question
If there is any acid in the rain in Howick.
B. This is how I will test my question
Collect rainwater over a couple of days. Then I'll make a indicator from purple cabbage. Then I will check the colour it turns to.
C. This is how I will make sure I have developed a fair test.
I would have collected water from a couple of days.
D. My hypothesis
I think that Howick will have no acid in it's rain.
E. Variables to be tested
The different days that I collect the rain.
F. Apparatus needed
Rain water, Purple cabbage, bottles, bottled water, a drinking straw, a knife, cotton,
G. Important points from my research
The chemical called anthocynin will change colour depending on the amount of ph in the water. Ph is used to measure acidity. Ph- 1=acid 7=water 14=highest-household chemicals. Acid rain is harmful to plants, animals and humans. Acid rain is caused by human impact. Ph 5.6 is acid rain.

Assessment Criteria
Excelling	Project is investigative, creative and original in design (has the X factor) Shows clear scientific method in use of controls and variables (if applicable) Procedure is detailed and feasible, and measurements planned Conclusion includes detailed analysis and interpretation of data/results Experiment has future application and purpose Log (if applicable) shows thoroughness of investigation
Extending	Project is designed to investigate a hypothesis Experimental design is original or adapted from books or other sources Shows scientific method Procedure is well planned and feasible Conclusion includes analysis and interpretation of data/results
Achieving	Project is designed to investigate a hypothesis Experimental design is minimally modified from books or other sources Shows scientific method Procedure requires more detail Conclusion includes some analysis and interpretation of data/results
Developing	Project is minimally investigative. Procedure minimally modified from books or other sources. Show some scientific method. Some planning in materials and equipment.
Emerging	Most information obtained from books or other sources Project attempted Little scientific method. Minimal planning in materials and equipment.
Teacher Comment: You chose an interesting science investigation Jay. Well done on your oral presentation. You were well prepared for it. You've worked hard on this task and presented your board really nicely. Mr Read.
